[Clinical Study of Enhanced Recovery after Surgery in Peri-operative Management of Total Hip Arthroplasty].

OBJECTIVE: To evaluate the clinical effect and rehabilitation benefit of enhanced recovery after surgery (ERAS) model in perioperative management of total hip arthroplasty (THA).
METHODS: A retrospective study were conducted in THA patients from the database of big data Research Center of Biomedicine, West China Hospital of Sichuan University from 2013 to 2016. The differences of rehabilitation quality, rehabilitation efficiency and hospitalization cost between ERAS model (ERAS group) and traditional model (traditional group) were compared.
RESULTS: 915 THA patients were included in the study, of which 497 patients were given ERAS peri-operative management and 418 patients in the traditional group. The rate of overall complications in the ERAS group was significantly lower than that in the traditional group (4.8% vs. 8.6%, P < 0.05), with lower rate of deep venous thrombosis (0.8% vs. 3.1%) and pulmonary infection (0.6% vs. 2.4%) in the ERAS group. Compared with the traditional group, the average length of stay in hospital was shorter in the ERAS group 〔(7.6±2.0) d vs. (10.9±2.9) d, P=0.039〕, as well as postoperative length of stay in hospital 〔(5.6±0.9) d vs. (8.6±2.0) d, P=0.028)〕. And the ERAS model reduced the total hospitalization cost by 4.8% to 7.1% (P < 0.05), of which the drug cost decreased by 17.2% to 24.9% (P < 0.05).
CONCLUSIONS: ERAS model in THA is safe and effective. It can reduce hospitalization cost and help to control medical cost. Copyright© by Editorial Board of Journal of Sichuan University (Medical Science Edition).
